Answer:
The error is in option 4) es intelligente y atletico.
Step-by-step explanation:
The error is in option 4) es intelligente y atletico. In English this means: he's intelligent and athletic. The correct spelling should be: Es inteligente y atlético. Inteligente in Spanish has only one L, and atlético has an accent mark in the E, as it's a word esdrújula (stressed on the antepenultimate syllable) and those words in Spanish always have an accent mark and it's considered an error to omit it.
